Description
The O11-D EVO / EVO RGB is an awesome case but it leaves a ~25mm gap between the side fans and the mesh panel, leading to a lot of air being recirculated.
I shaped these to maximise how much mesh area is used by each fan. Three of these dropped the fan speed to maintain loop temperature by 200rpm.
Tested on an O11-D EVO RGB, but may work fine on an O11-D VISION and some other models; test and let me know, also if you want deeper or shallower versions.
